力平衡

If the resultant force is zero, the force polygon draw with these forces is closed.

所以平面汇交力系平衡的必要与充分的几何条件是

The impeller can be used 90 years of the best self-balancing axial force hydraulic model, making pump bearings and mechanical seal life greatly extended.

叶轮采用90年代最优秀可自平衡轴向力的水力模型，使得泵轴承和机械密封使用寿命大大延长。

Hydrostatic bearing can solve the equilibrium problem of axial force of multistage centrifugal pump satisfactorily.

液体静压支承技术可以很好地解决多级离心泵轴向力的平衡问题。

We can see that the performance parameters in exactly the same circumstances, the submersible sewage pump horizontal axial force than the average, to a large pump, and the balance of the difficulty is harder than the vertical pump.

可以看出，在性能参数完全相同的情况下，潜污泵的轴向力比一般卧式泵要大，而平衡难度比立式泵要难。

In the Culmann analysis method, the assumption that the soil failure is in the mode of sliding along a plane is adopted; however only one force equilibrium equation along some special direction is utilized to derive the computation formula of earth pressure.

在Culmann分析方法中，沿用了Coulomb土压力理论关于平面滑动破坏的假定，而在推导土压力计算公式的过程中，仅利用了滑动体沿某一特定方向的一个力的平衡方程。

This consideration indicates that different inter- molecular forces are responsible for self-assembly and that gelation efficiency is the result of this delicate balance.

这一考虑表明不同的分子间的力对自组装起主导作用，而且凝胶形成效率是这一微妙平衡的结果。

Other Less Common Symptoms: A whole cluster of other symptoms appear during this infection, including progressive loss of hearing : that is, a gradually increasing deafness in older people (probably sensorineural hearing loss ); in younger people, a subtle loss of hearing acuity is noticed, meaning that it becomes a little more difficult to identifying environmental sounds, and more difficult to sensing their exact location; increased tinnitus ; sense of balance becoming noticeably less acute; dizziness spells; hoarse voice due to persistent throat soreness,(or possibly due to connective tissue damage in the larynx); chronic white tongue coating (called geographic tongue or migratory glossitis); red eyes (mild conjunctivitis, aka: pinkeye); infection of the urethra ; viral headache; eczema / psoriasis; large area of red greasy skin on the chest, just below the neck; increased hair loss; cold hands and feet; slow wound healing; weight gain on stomach; kidney pains ; joint pains; muscle cramps , especially in the calf muscles; sudden episodes of racing heart and heart palpitations; acute pericarditis; aseptic meningitis; reduced attention and concentration; forgetting words, losing some of your vocabulary, suddenly having more difficulty in spelling words and remembering information; frequently selecting incorrect words while talking (and strangely, sometimes selecting a word which is incorrect, but from the same category as the right word for example, saying "pun" when you meant to say "irony" both are in the same category of literary devices).

其他较常见的症状：对整个集群等症状出现在这个感染，包括听力逐渐丧失，即：在老年人耳聋逐渐增加（可能是神经性听力损失），在年轻人，一个微妙的听力丧失视力注意到，这意味着它变得有点更加难以确定的环境声音，更难以检测他们的确切位置，增加耳鸣，平衡感越来越明显那么尖锐，头晕法术；嘶哑的声音，由于持续的咽喉疼痛，（或可能是由于在喉部结缔组织损害），慢性白苔，红色的眼睛（轻度结膜炎，又名：火眼），尿道感染，病毒性头痛，湿疹/牛皮癣，大面积红油腻皮肤的胸部，颈部下方，增加脱发；手脚冰冷，伤口愈合缓慢，体重在胃增益；肾痛苦；，关节痛，肌肉痉挛，特别是在小腿肌肉，突然心脏病发作的赛车和心悸，急性心包炎，无菌性脑膜炎；减少，注意力和集中力，忘记的话，失去的一些词汇，突然有更多的拼写字和困难记住信息；经常选择不正确的话，而谈话（和奇怪的是，有时一个单词的选择是不正确的，但是从文字的权利-例如同一类，称"双关"当你的意思是说"讽刺"-无论是在文学设备同一类）。

For instance,those poses such as hands-up,legs-lifting and headstand are beneficial for children's viscera,arms and legs,balance and mind.

亲子瑜伽的动作设计非常符合宝宝成长发育规律，其中像举手、抬腿、倒立、等动作，对宝宝的内脏、肢体发育都有良好作用，而且还能锻炼宝宝平衡感、专注力。

Hydrostatics researches the mechanical rules when liquid is balancing. Hydrodynamics researches the mechanical rules when liquid is moving, include the relationship between the force that put on in liquid and quantum of physics, which represent liquid moving style, the rule of liquid moving characteristic and energy conservation and transform.

水静力学是研究液体处于平衡状态时的力学规律，水动力学是研究液体处于运动状态时，作用于液体上的力与表征运动状态的各种物理量之间的关系，以及液体的运动特性与能量守恒和转换的规律。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
